My 10 year old dauther is shooting a XD 9 with cast 121 gr flatnose bullet about 1.080 long. When she unloads and shows clear many times the bullet will be stuck in the chamber like a 40sw with a glock bulge. It also happens while hand cycling the bullets thur the gun. Sometimes the bad bullet will do it more then once, sometimes it won't. Today while cycling some of the MG 124gr bullets loaded to 1.125 by hand they would hang up with the slide about half way back. A few light jerks would work it the rest of the way out. I tightened the crimp and it helped some. Any help would be appreciated. Hoping to get this cleared up before she shoots Double Tap.
